| 摘 要： | 根据金矿产出的地质背景，可将本区金矿分为产于绿岩带的中金矿及产于花岗岩侵入体中的金矿两类，但不论哪类金矿，其成矿物质都主要来自绿岩带，燕山早期重熔花岗岩浆活动为成矿提供了热源及部分矿质，介质，赋矿构造主要为西太平洋板块活动的所产生的ＳＮ向，ＮＥ向，甚至ＮＷ向的断裂或断裂破碎带，成矿期为燕山（早）期。

| Abstract: | On the basis of the geologic setting of gold occurrence,it can be divided into two types in the gold mining area,i.e.gold bearing minerals in greenstone belt or granitic intrusion.Nevertheless,the total ore forming substances were derived mainly from greenstone belt.The Yanshanian redissolved granite magma activities resulted in formation of heat source,partial minerals,media for the mineralization.The host structure is mainly SN and NE trending,even more NW fault and fault fractured zone by the western Pacific plate activities.Main mineralization epoch is an early Yanshanian. |
